Be sure to note Domenic's caveat about more than 2 values being included in
the formula if the percentages are duplicated. It would affect the formula I
posted as well.

If your data is in A1:C9 and

A13 = T1
A14 = T2
A15 = T3

Enter this in B13 (Confirmed with Control+Shift+Enter after typing it into
the formula bar-if you do it right excel will put braces { } around the
formula) and copy down.

=SUM(($A$1:$A$9=A13)*($C$1:$C$9=LARGE(IF($A$1:$A$ 9=A13,$C$1:$C$9,0),2))*($B$1:$B$9))
